## [NoClassDefFoundError: org/slf4j/LoggerFactory和NoClassDefFoundError: org/apache/log4j/LogManager解决方法][NoClassDefFoundError_ org_slf4j_LoggerFactory_NoClassDefFoundError_ org_apache_log4j_LogManager] ##

1.如果运行程序出现错误：“Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory”，这是因为项目缺少slf4j-api.jar和slf4j-log4j12.jar这两个jar包导致的错误。

2.如果运行程序出现错误：“java.lang.NoClassDefFoundError: org/apache/log4j/LogManager”，这是因为项目缺少log4j.jar这个jar包

3.错误：“Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.MDC.getCopyOfContextMap()Ljava/util/Map”，这是因为jar包版本冲突造成的。

slf4j-log4j12.jar版本信息：

log4j.jar版本信息：

![复制代码][copycode.gif]

Manifest-Version: 1.0
    Ant-Version: Apache Ant 1.6.5
    Created-By: 1.3.1_18-b01 (Sun Microsystems Inc.)

    Implementation-Title: log4j
    Implementation-Version: 1.2.14
    Implementation-Vendor: "Apache Software Foundation"

后来将log4j.jar版本从上面的1.2.14换到1.2.11

Manifest-Version: 1.0
    Ant-Version: Apache Ant 1.6.4
    Created-By: 1.4.2_06-b03 (Sun Microsystems Inc.)

就不再出现“Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.MDC.getCopyOfContextMap()Ljava/util/Map”错误了。

4.ActiveMQ错误：Wire format negociation timeout: peer did not send his wire format.

官方解释：[http://activemq.apache.org/javaxjmsjmsexception-wire-format-negociation-timeout-peer-did-not-send-his-wire-format.html][http_activemq.apache.org_javaxjmsjmsexception-wire-format-negociation-timeout-peer-did-not-send-his-wire-format.html]

我出现这样的错误主要是因为ActiveMQ与slf4j的版本有冲突，我原先使用的是以前一种用的slf4j-1.4。后来看apache-activemq-5.5.1\\lib目录下有slf4j-api-1.5.11.jar、slf4j-log4j12-1.5.11.jar和log4j-1.2.14.jar。我想这几个jar应该是和ActiveMQ匹配的，就使用了这三个jar，最终错误解决。
